you do realise you're that the haunted crone's dome is worth less than the unique crone's dome

I have seen some with B/O of 2 keys, so I would say 2-3 keys is the better range, because there are enough 3 keys B/O ones, so people dont jump on the 4 keys ones

It was 2 normal keys, I was tempted to grab it but after what happened with the fall crate items, I'm waiting to buy the things I like on the last days of halloween, anyway, I've just search for it on outpost, and it looks like 4 keys B/O are ignored, They are selling at 3 keys, tho they are plenty of them avaible at that price, and some are being sold at less than 3 keys (not that many yet):

http://www.tf2outpost.com/trade/5671358 Sold for either 1 eerie key or 2 normal keys

http://www.tf2outpost.com/trade/5675207 Sold for 1 key+ Haunted Spooky Shoes

http://www.tf2outpost.com/trade/5690580 Sold for either 2 keys or a 1:1 with other Haunted

There are not that many on sale for less than 3 keys, so I guess 3 keys is the on going price, but definetly not 4, 2 eire keys = 3 normal ones at this point, that's why I said none of your links show a 4 keys successful sale.

That said, I've been holding myself from suggesting a lower price on the items that I was interested in buying because I think I could be biased toward their price, still since I'm keeping an eye on them I like to comment to share what I'm seing about those items, I hope you understand what I'm saying :P
